Abstract: A Helmet Integrated Display (HID) system and device for remotely viewing a video signal, wherein the device is worn on a cameraman's head. The device has a housing containing a head-mounted, high resolution CRT to produce a visible image from an incoming video signal generated by an input video source such as a STEADICAM video tap camera. Through a network of mirrors and a double convex lens, the visible image is converted into a virtual image, which image is presented to a sighting eye of the cameraman. An occlusion device, also attached to the HID system, partially blocks off the view out of a non-sighting eye such that the perceived images from both eyes combine in the cerebral cortex of the cameraman's brain into one coherent image without problems of binocular rivalry.

Abstract: An apparatus is disclosed for propelling a person in an underwater environment. The apparatus includes a hull assembly for maintaining the apparatus at the desired level of buoyancy, the hull assembly having a longitudinal axis. Support means are provided for allowing the person to position the hull assembly at the desired angular orientation relative to himself. Thruster means are connected to the hull assembly for propelling the apparatus through the water. The thruster means are positionable at the desired angular orientation relative to the longitudinal axis of the hull assembly. The hull assembly is angularly oriented independently of the direction of the movement of the apparatus. Means are provided for connecting the thruster means to the hull assembly.
